NEEDLE-RAIL FOR COTTONS KNITTING-FRAMES.

SPECIFICATION forming part of Letters Patent No. 476,959, dated June 14, 1892. Application filed November 4, 1891. Serial No. 410,877. (No model.)

To 62/ whom, it may concern.-

Be it known that I, FRIEDRICH ANTON LUD- WIG, a subject of the German Emperor, and a resident of Chemnitz, Germany, haveinvented a certain new and Improved Needle-Rail for Cottons Knitting-Frames, of which the following is a full, clear, and exact description.

The object of my present invention is to provide a needle-rail for Cottons knittingframes, by means of which the bending of the needles and damaging of the goods being manufactured, which so often occurs in making the course, may be entirely obviated.

It is well known that the needles in Cottons knitting-frames are considerably longer than those of any other frames, and,besides this, are generally flat,so that the slightest influences such as knots or impurities in the yarn-are sufficient to bend the needles sidewise, in the direction of the section, thus breaking oif the points of the same or bending them, tearing holes in the ware, or damaging the sinkers, &c. By means of the rail hereinafter more particularly described this disadvantage is entirely obviated in that the said rail, which may be provided with small notches or depressions for the needles, is arranged to rest against the row of needles, supporting each needle just at that point where it would otherwise be most likely to bend or break under the influences before mentioned.

The main advantage of my improved needle-rail is that the same in either of the abovementioned emergencies does not require tobe taken out or removed from the frame, but is simply turned upward Without causing any further inconvenience. My improved needlerail, furthermore, enables the employment of much inferior kinds of yarn than heretofore. The quality of the goods manufactured is also improved by the employment of my device, as the needles cannot give or bend in making the course and a backward movement of the sinkers is prevented.

In order to make this specification more easily intelligible, I refer to the accompanying drawings, in which similar letters denote similar parts throughout the several views.

Figure 1 shows an end elevation of my improved device. Fig. 2 is a front elevation of the same. Fig. 3 shows the needles in front and side elevation. Fig. at shows needles which have been bent in making the course, and Fig.5 is a detail partial plan of a recessed needle-rail.

Only so much of a Cotton loom is shown in the drawings as is necessary in order properly to illustrate and explain my invention. The spindles e are arranged in brackets gnear the narrowing-bar f, each bracket g being arranged to support two spindles, as may be seen in Fig. 2. The needle-rail, which is beveled off at the side coming in contactwith the needles, is carried by the arms Z1, mounted on the spindles c and having collars for holding the same in position, being secured by means of set-screws. The arms I) are provided with weights o 0, cast onto the same and which have the tendency to hold the needle-rail a with a certain amount of pressure against the needles m. Pressure-springs may be substituted for the weights 0 if found desirable. In narrowing it is necessary to remove the needle-rail from the needles. This is accom plished in the following manner: hen the narrowing-bar, which is pivoted at It, is lowered, the shaft f of the same slides along the curve d of the arm I), pushing back the rail 0, from the needles m. On raising the narrowing-bar again the rail a falls back onto the needles under the influence of the weights 0 or their equivalents. The rail to may also be provided with recesses for the reception of the needles, as shown in Fig. 5. If it is desired to remove the rail an entirely from the needles, the same may be turned upward until the rest It on the upper part of armb comes to lie on the nose 1' of brackets g.

Having now particularly described and ascertained the nature of my invention and the manner of using the same, I declare that what I claim is- 1. In a Cotton knitting-frame, in combination, a swinging needle-rail suspended by arms I) from spindles e, mounted in brackets g, and provided with weights 0, substantially as described.

2. The combination,with the brackets g, having mounted therein spindles e, carrying arms Z), having curved interior sides 61 and weights 0 and carrying needle-rail a, of the shaft f of the narrowingbar, substantially as described.

3. The combinatiomwith the arms I), mount- In witness whereof I have hereunto set my ed on spindles e and carrying rail a and prohand in presence of two witnesses. vided with weights 0, arranged as described, 7 of the brackets g and the arms I), having the FRIEDRICH AN'I ON LUDWVIG' 5 rests k,adapted to lie upon projection i of the Witnesses:
